Defensive publication

ABSTRACT

DISCLOSED IS A PROCESS FOR PREPARING POLYESTER CARPETS THAT WILL PASS THE METHENAMINE TABLET TEST COMPRISING APPLYING TO A CARPET OF POLYESTER FIBER AN ORGANIC BROMINE COMPOUND OF AT LEAST 6 CARBON ATOMS, THE ORGANIC BROMINE COMPOUND CONTAINING, BASED ON THE WEIGHT OF THE ORGANIC BROMINE COMPOUND, FROM ABOUT 40 TO ABOUT 85 WEIGHT PERCENT BROMINE, AND THEREAFTER, HEATING THE FIBER IN A TEMPERATURE RANGE OF ABOUT 100 TO ABOUT 220* C. FOR A SUITABLE TIME TO DIFFUSE INTO THE FIBER STRUCTURE A SUFFICIET QUANTITY OR ORGANIC BROMINE COMPOUND TO RESULT IN, BASED ON THE WEIGHT OF THE FIBER, FROM 0.5 TO 2.0 WEIGHT PERCENT BROMINE IN THE FIBER STRUCTURE.
